Scottsdale police say officers went to Maxwell’s home Saturday night after getting a call about a person with a gun.

Maxwell didn’t say much during his arraignment Sunday where he faced charges of aggravated assault with a deadly weapon and disorderly conduct.

“Your Honor, he’s never really had any type of criminal activity before in his life and as you probably know he’s a catcher for the Oakland Athletics,” his attorney could be heard saying during the arraignment.

Maxwell had previously gained notoriety as the only player in major league baseball to take a knee this year during the national anthem to protest racial injustice.

John Shea has been covering baseball in the Bay Area for the San Francisco Chronicle for almost 30 years. He says the situation with Maxwell’s protest was something he’s never seen before.

“Baseball has a different culture than basketball and football. You see more reserved attitudes in baseball. You see people who don’t show emotion,” said Shea. “When someone goes against the norm and turns left when everyone turns right, then he’s noticed.”
